The main character should have a voice. I know it's ME in the role of the Devine One, but now it feels as if I'm playing with a mute! He has absolutely no appeal whatsoever, which is a real shame.
The Deathknight is OK, his voice COULD be better and his humor is very bland (like the humor in the whole game, it's no Fallout!), but replacing him is not an option anymore. All in all he fits well in the game, but I don't think he is what Larian wanted him to be.
The Deathknight and the Devine One are stuck together, two opposites who have to put up which each other! This is not what I see in the current setup. The Knight seems to be OK with the Devine One and vice versa. Why not a few funny one-on-ones between deathknight and the devine one? Make it nice and snappy with a wink and a nudge... Think Monty python or buddy movies...
